The direction shown in arrow in Fig. 2 is the travel direction of the first push rod 103.
Shown in figure 3, Fig. 3 discloses the local structural graph of this auxiliary mechanism, displaying be the structure at the back side of operating mechanism main body. As shown in the figure, slide block 109 and snap close 110 it is furnished with at the back side of operating mechanism main body 101. Transmission rod 102 is arranged in the top of operating mechanism main body 101, and extends partially in operating mechanism main body 101. Although all visible transmission rod 102 in figs. 2 and 3, because transmission rod 102 mainly coordinates with the parts being arranged in operating mechanism main body 101 back side, therefore composition graphs 3 is introduced together. Composition graphs 1 is visible, and cam assembly comprises three parts: 111a, 111b and 111c. The cam assembly 111a of first part is connected with rotation handle 112, is illustrated as the gear being arranged in horizontal plane. The cam assembly 111b of second section is engaged with the cam assembly 111a of first part, is illustrated as the gear being arranged in vertical plane. First part and second section 111a, 111b are engaged transmission mutually. The cam assembly 111c of Part III is connected with the cam assembly 111b of second section, and both linkages, the cam assembly 111c of Part III is arranged in operating mechanism main body 101, and links with the slide block 109 being arranged in operating mechanism main body 101 back side. Transmission rod 102 is subject to outside excitation and action, and such as, when being subject to outside dropout and encourage, transmission rod 102 can action band movable slider 109 and snap close 110 move. Transmission rod 102 is connected with slide block 109 and snap close 110. The middle part of slide block 109 has chute 191, and in the illustrated embodiment in which, chute 191 is in oblique extension. Having projection 192 on the cam assembly 111c of Part III, projection 192 is arranged in chute 191. When the position of slide block 109 is moved, movement is also followed in the position of chute 191, projection 192 can be driven to move when cam assembly 111c rotates, and band movable slider 109 moves.
The auxiliary mechanism that Fig. 4 discloses the operating mechanism according to one embodiment of the invention carries out threading off the schematic diagram of instruction. As shown in Figure 4, when being subject to outside dropout excitation, movement is promoted snap close 110 to rotate by transmission rod 102, and snap close 110 rotates and operating mechanism main body 101 is threaded off. In the moving process of transmission rod 102, transmission rod 102 promotes slide block 109 to move simultaneously, and slide block 109 will be pushed into the position specified, and this position specified is relevant with the mobile position of transmission rod 102. Cam assembly can be in free movement state after operating mechanism main body 101 is threaded off, and can reset under the effect of the resetting mechanism (such as return spring) of self. Owing to cam assembly forms linkage by three parts, the projection 192 of the cam assembly 111c of Part III is arranged in the chute 191 of slide block 109, thus can receive the impact of slide block 109 position. In an embodiment, when outside excitation is threaded off, slide block 109 can slide into specified location, by its chute 191 and projection 192, the rotation angle of the cam assembly 111c of Part III is limited in specified location, and then the linkage by other two parts of cam assembly, realize outside excitation trip status instruction by cam assembly. In an embodiment, in the process of upper button, rotating and rotate handle 112, drive cam assembly to rotate, the cam assembly 111c of Part III promotes slide block 109 to move by the interaction of projection 192 and chute 191. Slide block 109 makes it no longer near snap close 110 after moving, such snap close 110 has the space of free movement. When transmission rod 102 is subject to outside dropout actuation signal, transmission rod 102 only needs to promote snap close 110, and the linkage of the parts of comparatively small amt is conducive to reducing the resistance of motion, fast reaction speed.
The auxiliary mechanism that Fig. 5 discloses the operating mechanism according to one embodiment of the invention carries out testing the schematic diagram threaded off. As shown in Figure 5, test dropout can be carried out by stirring the first push rod 103. Stir push rod and dial block 131, promote the first push rod 103 to move along the direction shown in the arrow in Fig. 2. In the process that test is threaded off, the first push rod 103 directly contacts with the 2nd push rod 104, and namely the front end of the first push rod 103 directly touches the upper end of the 2nd push rod 104, and in the process that test is threaded off, U-shaped connecting rod 108 does not play a role. First push rod 103 directly acts on the 2nd push rod the 104, two push rod 104 and moves downward, and drives tumbler 105 to rotate, and tumbler 105 rotates and drives lever 106 to rotate. As shown in Figure 5, after lever 106 rotates, snap close 110 can be stirred by the top branch of lever 106 so that snap close 110 rotates, and snap close 110 drives tripping mechanism main body 101 to thread off after rotating.
The auxiliary mechanism that Fig. 6 discloses the operating mechanism according to one embodiment of the invention carries out the schematic diagram of isolation processes. In isolation processes, the basis that the test shown in Fig. 5 is threaded off is continued promote the first push rod 103 to move along the direction of arrow shown in Fig. 2. Now the first push rod 103 no longer directly contacts with the 2nd push rod 104, and in isolation processes, U-shaped bar 108 plays a role, and plays the function of linkage the first push rod 103 and the 2nd push rod 104. After first push rod 103 continuation is mobile, continued by U-shaped bar 108 to promote the 2nd push rod 104 to move down. 2nd push rod 104 drives tumbler 105 to rotate further, and then drives lever 106 to rotate further. The lower section branch of lever 106 pushes down pull bar 107 (can with reference to figure 5) after rotating, by pull bar 107 push down further lower section contact supporting assembly 114 and and contact bridge 115, complete isolation action. The stroke that the existence of U-shaped bar 108 makes the 2nd push rod 104 to move down is bigger so that the stroke of corresponding tumbler 105 and lever 106 is also bigger, thus obtains the power of bigger downward compacting pull bar 107. Meanwhile, after the first push rod 103 moves through certain stroke, the first push rod 103, U-shaped bar 108 and the 2nd push rod 104 form a structure dead point. Structure dead point makes the position of three kinds relatively be fixed, and thus obtains stable isolation state.
When resetting, operating mechanism main body 101 has been in dropout or off position. On this basis, rotating and rotate handle 112, drive cam assembly to rotate, the cam assembly 111c of the Part III in cam assembly is moved by the chute 191 band movable slider 109 in projection 192 and slide block 109. Slide block 109 produces two effects after moving: first effect drives transmission rod 102 to rotate after slide block 109 moves to reset, it is achieved the reset operation of transmission rod 102 after excitation is threaded off in outside. 2nd effect is that slide block 109 drives snap close 110 to reset, and after snap close 110 resets, lever 106 also resets thereupon. The reset of lever 106 can rely on himself resetting mechanism or have other parts to drive and reset. In one embodiment, under a kind of application model, when the dynamic lever 106 of cam assembly indirect belt resets, cam assembly also can drive pull bar 107 to move, and drives the contact supporting assembly 114 of lower section and contact bridge 115 to reset so that contact resets from disconnection position.
The process described above action under outside incentive action that is all operating mechanism, the process driving contact to disconnect, can be considered it is disconnection process under normal running or non-shorting fault. If the fault of being short-circuited, then it not perform disconnection operation according to above-mentioned process. Return to shown in Fig. 1, when being short-circuited fault, execution be scold out process: contact is scolded out by the electrodynamic repulsion force of short-circuit current, drives contact bridge 115 and contact supporting assembly 114 to move down. After contact supporter assembly 114 moves down, the pull bar 107 being attached thereto moves down, the hook portion of pull bar 107 end pulls the projection of the lower section branch end being positioned at pull bar 106, under the effect of pull bar 107, the lower section branch of pull bar 106 moves down, then stirring snap close 110, after snap close 110 is struck, band pneumatic operating mechanism main body 101 is threaded off. Perform process described above afterwards, contact is maintained on the position of disconnection. Scolding out process to perform the quick protection of standby, supplementary structure can when without impelling operating mechanism main body to perform a point disconnected protection when outside conventional dropout signal. Scolding out in process, only having contact supporting assembly 114, contact bridge 115, pull bar 107, lever 106 and snap close 110 to participate, the number of parts of participation is few, and volume is little, is conducive to scolding starting and completes as early as possible, it is to increase corresponding speed. And remaining parts be all snap close 110 be struck cause operating mechanism main body 101 thread off after participate in again, now contact has been in disconnection state.

Also operating mechanism main body 101 can be made to thread off under the effect that transmission rod 102 encourages in outside. When there is short trouble, contact is scolded and is driven rear pull bar 107 and can pull lever 106, also can cause the dropout of tripping mechanism main body 101. And rotate rotation handle 112 and by cam assembly, each parts of operating mechanism main body 101 and auxiliary mechanism can be resetted, return to the state of closed connection. When promoting the first push rod 131 to carry out isolation operation, it is necessary to mechanism lock is decided to be isolated location, does not allow to reset. So, shown in figure 7b, when carrying out isolation and operate, by handle pulling block 113 from rotating pull-out handle 112, as shown in the figure, handle pulling block 113 has lockhole, lockhole is settled padlock, it is possible to stop handle pulling block 113 to return to and rotate in handle 112.
